What Instrument Is Used to Measure Density? | Reference.com

Some commonly used density measuring devices include hydrometers, aerometers, pycnometers, density kits and digital density meters. The density of an object can be manually computed by dividing its mass by its volume, which is mathematically represented by the formula d = m/v, where "d" denotes density, "m" indicates the mass and "v" is the volume of the object.
